[0026] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0027] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0029] The embodiment of the utility model provides a locking device which is easy to unlock, such as Figure 1-3As shown, the chassis 100 includes a locking member 200, a rotating member 300 and an elastic member 400. The locking member 200 includes a stopper 210 for blocking the goods, and the stopper 210 is used to block the movement of the goods, thereby positioning the goods. The locking member 200 and the rotating member 300 are both rotatably connected to the chassis 100, and the rotation axis of the locking member 200 and the chassis 100 and the rotation axis of the rotating member 300 and the chassis 100 are parallel. The locking member 200 can rotate on the same or parallel plane with the rotating member 300, which creates conditions for the rotation of the rotating member 300 to drive the rotation of the locking member 200. The locking member 200 can rotate relative to the base frame 100 to a locked state and an unlocked state. When the locking member 200 is in the locked state, the stopper 210 is located on the moving path of the goods to lock and position the goods; when the locking member 200 is in the unlocked state, the stopper 210 will move out of the moving path of the goods, thereby no longer blocking the goods, so that the goods can move along the conveying direction. The two ends of the elastic member 400 are respectively connected to the locking member 200 and the base frame 100. The elastic member 400 applies a pulling force to the locking member 200. Under the pulling force of the elastic member 400, the locking member 200 remains in the locked state. Therefore, in the absence of other external forces, the stopper 210 can continue to lock and position the goods to prevent the goods from falling from their placement position. The rotating member 300 is slidably connected to the locking member 200. When the entire locking device needs to be unlocked, an external trigger device, such as a push rod, can apply a thrust to the rotating member 300. When the rotating member 300 is subjected to sufficient external thrust, it will rotate relative to the base frame 100, thereby driving the locking member 200 to overcome the pulling force of the elastic member 400 and rotate to the unlocked state, thereby completing the unlocking of the locking device. Therefore, by applying a thrust to the rotating member 300, the locking member 200 can be rotated from the locked state to the unlocked state, which facilitates the unlocking of the entire locking device. At the same time, this embodiment realizes locking and unlocking through the transmission of a mechanical structure, which is more stable and reliable.

[0030] In some embodiments, the rotating member 300 is provided with a wheel body 310 rotatably connected to the rotating member 300, and the wheel body 310 is parallel to the rotation axis of the rotating member 300 and the rotation axis of the rotating member 300 and the base frame 100, and the wheel body 310 is used to bear the external thrust. When the external thrust acts on the wheel body 310, a component is generated on the wheel body 310, thereby allowing the rotating member 300 to rotate relative to the base frame 100, and another component can allow the wheel body 310 to rotate relative to the rotating member 300, so as not to affect the external thrust and continue to move in the original direction. Therefore, the force applied by the outside to the wheel body 310 can maintain the same direction without changing with the rotation of the rotating member 300, which further facilitates the unlocking of the entire locking device.

[0031] by Figure 1For example, an external trigger device can push the wheel body 310 from front to back. Since the wheel body 310 can rotate, while the wheel body 310 rotates relative to the rotating member 300, the wheel body 310 drives the rotating member 300 to rotate relative to the base frame 100, and the force applied by the trigger device to the wheel body 310 can maintain the same direction.

[0032] Among them, a support rod can be fixed on the rotating member 300, and the wheel body 310 can be a bearing sleeved on the support rod, which has better smoothness.

[0033] In some embodiments, the locking member 200 further includes a locking rod 220 extending in the front-to-back direction, and the stopper 210 is fixed to the top of the locking rod 220. The rotating member 300 is arranged at the front side of the locking rod 220, the rear end of the locking rod 220 is rotatably connected to the base frame 100, and the front end of the locking rod 220 is slidably connected to the rotating member 300 along the extension direction of the locking rod 220. When the end of the rotating member 300 connected to the locking rod 220 rotates downward, the sliding of the rotating member 300 relative to the locking rod 220 will apply a rotational driving force to the locking rod 220, so that the locking rod 220 rotates, and the rotation of the locking rod 220 will drive the stopper 210 on the top thereof, thereby changing the height of the stopper 210, and realizing the switching of the locking member 200 between the locked state and the unlocked state.

[0034] Furthermore, the locking rod 220 is provided with a sliding groove 221, the extension direction of the sliding groove 221 is parallel to the extension direction of the locking rod 220, and the sliding rod 320 is fixed on the rotating member 300, and the sliding rod 320 is inserted into the sliding groove 221 and can slide along the sliding groove 221, thereby realizing the sliding connection between the rotating member 300 and the locking rod 220. Among them, the sliding rod 320 can be sleeved with a bearing to increase the smoothness of the sliding rod 320, making it easier to slide in the sliding groove 221.

[0035] Furthermore, the sliding groove 221 passes through the locking rod 220, and the rotating member 300 includes two rotating plates 330, which are respectively located on both sides of the locking rod 220, and the sliding rod 320 passes through the sliding groove 221, and the two ends of the sliding rod 320 are respectively connected to the two rotating plates 330, so that the sliding rod 320 is difficult to escape from the sliding groove 221, thereby ensuring the stability of the sliding connection between the rotating member 300 and the locking rod 220.

[0036] The wheel body 310 of the above embodiment may also be disposed between two rotating plates 330 .

[0037] In some embodiments, a limiting member 500 is also fixed on the bottom frame 100. When the elastic member 400 pulls the locking member 200 to abut against the limiting member 500, the locking member 200 remains in the locked state. On the one hand, the limiting member 500 can accurately locate the position of the locking member 200 when it is in the locked state, avoiding position deviation, so that the goods can be accurately locked and positioned. On the other hand, due to the existence of the limiting member 500, the elastic member 400 can exert a relatively large force to prevent the locking member 200 from rotating to the unlocked state at will.

[0038] Furthermore, a first fixing plate 110 is provided on the bottom frame 100, and the limiting member 500 is connected to the first fixing plate 110, and the limiting member 500 can move relative to the first fixing plate 110 along the pulling direction parallel to the elastic member 400. Since the locking member 200 is in a locked state when it abuts against the limiting member 500, when the position of the limiting member 500 changes, the position of the locking member 200 in the locked state will also change accordingly, so that the position of the locking member 200 in the locked state can be adjusted to adapt to the needs of the cargo placement position.

[0039] In this embodiment, the first fixed plate 110 can be provided with a threaded hole extending therethrough, and the extension direction of the threaded hole is parallel to the tension direction of the elastic member 400. The limiting member 500 is a screw threadedly connected to the threaded hole. By screwing the screw, the extension length of the screw can be changed, thereby adjusting the position of the locking member 200 when it is in the locked state.

[0040] Among them, the tail end of the locking rod 220 is connected to a connecting rod 230 extending downward, the screw can extend in the front-to-back direction, the pulling direction of the elastic member 400 on the locking member 200 can also extend in the front-to-back direction, and the end of the screw abuts the connecting rod 230, thereby limiting the rotation of the entire locking member 200.

[0041] In some embodiments, the locking device for facilitating unlocking further includes an adjusting mechanism 600, one end of which is connected to the base frame 100, and the other end of which is connected to the elastic member 400. The adjusting mechanism 600 is used to adjust the pulling force of the elastic member 400 on the locking member 200 to change the magnitude of the pulling force so that it is compatible with an external trigger device.

[0042] Further, the adjustment mechanism 600 includes an adjustment rod 610 and a fastener 620. The bottom frame 100 is provided with a second fixing plate 120. The adjustment rod 610 can slide relative to the second fixing plate 120 in a direction parallel to the tension of the elastic member 400, and the adjustment rod 610 is connected to the elastic member 400. When the adjustment rod 610 slides relative to the second fixing plate 120, the length of the elastic member 400 can be changed, thereby adjusting the tension of the elastic member 400 on the locking member 200. The fastener 620 is used to fasten the adjustment rod 610 to the second fixing plate 120 or to loosen the adjustment rod 610. When it is necessary to adjust the tension of the elastic member 400 on the locking member 200, the fastener 620 is used to loosen the adjustment rod 610, and the adjustment rod 610 can slide relative to the second fixing plate 120 to change the length of the elastic member 400. After the tension of the elastic member 400 on the locking member 200 is adjusted, the fastener 620 is used to fasten the adjusting rod 610 , and the adjusting rod 610 cannot slide relative to the second fixing plate 120 , thereby maintaining the adjusted state.

[0043] The second fixing plate 120 may be provided with a through hole extending through it, the extension direction of the through hole being parallel to the pulling force of the elastic member 400 on the locking member 200, the adjusting rod 610 being provided in the through hole and being able to slide along the through hole, so that the adjusting rod 610 can slide relative to the second fixing plate 120 in a direction parallel to the pulling force of the elastic member 400. The adjusting rod 610 may be provided with threads, the fastener 620 includes two nuts sleeved on the adjusting rod 610, the two nuts are respectively located on both sides of the second fixing plate 120, the adjusting rod 610 can be fastened to the second fixing plate 120 by tightening the two nuts, and the adjusting rod 610 can be loosened by loosening the two nuts.

[0044] In some embodiments, a reflector 240 is fixed to the locking member 200, and a photoelectric sensor is also provided at the location where the goods are placed, and the photoelectric sensor can detect the reflector 240 when and only when the locking member 200 is in the locked state. In this way, it can be determined whether the locking member 200 is in the locked state, so that the conveying device can perform the next step.

[0045] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
